      @anthonyh Google code 43 NVIDIA...... Basic translation is we want to stop you doing this with a consumer card in a VM. There are solutions I believe.

        Yes, using Nvidia card supporting GPU passthrough 😛

        Otherwise, there's "border line" patches on Windows drivers available on GitHub, but we won't find those for you 😉

          @linhnb don't think you can use the GUI for GPUs, only vGPUs.

          RX580 does work, just follow the PCI passthrough guide.

            AMD cards are indeed far better for both vGPU and GPU passthrough: it just works.

              If only they made a LP vGPU card.... Looks like a WX4100 will have to do.

                @anthonyh yeah, I also got this note in version 8.1. I just don't know why. But my VM can't see Rx580, that's the problem

                @olivierlambert man, please, I got problem right here with AMD GPU. Please help.

                @jmccoy555 You can use the GUI. I checked, the code changes as if you do make it in CLI. please check the newest version 8.1

                  Well, this card is technically in the Quadro family, so I was hoping it'd work. I see solutions for libvirt/KVM, but not Xen. Any "nudge" would be greatly appreciated if anyone is willing. This is just a test environment. If the application works in this setup we'll buy proper hardware and go the AMD route.

                    I think I might have found the GitHub driver patch @olivierlambert was referring to...

                        Thanks for the tip!! Working in 8.1 in XCP-ng Center and also XO 🙂

                        Also, dont think there is a need to 'hide' the GPU from Dom0 now??

                        edit: Did a fresh install, no need to 'xen-pciback.hide' when assigning via XO or XCP-ng center. This was with AMD as they play nicely, not sure about NVIDIA.

                              @imtrobin No, AMD. Currently a WX4100 (as its LP and fits into a 2U server) but have also had a RX580 working before.
